Parent caries-f FREDERICK W. PETERS, OF CLEVELAND, OHIO, ASSIGNOR TO SPICEBIVTANUFACTUR- UNIVERSAL JOINT.

Application filed April 22, 19a5.- serial 1-Io.'24,927.

This invention relates to universal joints, and moreparticularly to oints of the character whereinthe trunnions on the end coupling members are connected with an interof seats extending laterally therethrough,

while preventing the leakage of'lubricant from the ends of said seats.

A further object of the invention is to provide a joint of this character which is simple in construction and cheap of production.

I accomplish the foregoing objects in and through the construction and arrangement of parts shown in the drawings, wherein Fig. 1 represents a sectional elevation of a universal joint embodying my invention; Fig. 2 a central sectional view'through the ring showing the pins and trunnions in elevation; Fig. 3 a sectional elevation of the joint, the viewjbeing taken at the left of the connecting ring and close to the clamping ring 18; Fig. 4: a central sectional view through said ring; and Figs. '5 and 6'are views in side and end elevat1on, respectively, p

of one of the bearing blocks. I

Describing the various parts by reference characters, 1 and 2 denote hubs by means of which the joint is connected to shaft sections (not shown) the hub 2 being shown as adapted for a splined connection with its shaft section, the outer end of the hub bore being closed by a plate 3. The hubs are pro- 'vided each with a yoke, the arms 4: of each yoke having a cross pin 5 mounted therein, the outer ends 6 of each cross pin constituting trunnions. Each cross pin is shown as provided with a central recess 5 of slighty greater p h than the radiu 9 hem,

SOUTH PLAIINFIELD, NEW- JERSEY, A CORPORATION OF each recess being about 210 in angular eX- tent to accommodate the rocking movements of the p1ns. The trunnions are adapted to be mounted 111 bearing blocks'carried by and supported within a connecting member in the form of a ring, the ring being indicated generally at A. The ring is preferably made from malleable iron and is provided with an outer cylindrical wall 7, annular side walls 8 and 8 and an inner cylindricalwall 7 the inner wall being segmental.

Formed in the ring thus provided are transversely extending seats B for" the hear ing blocks. These seats extend through the side wall 8? and toward and through the opposite side wall 8; and the block-receiving inner wall of each such seat is a section of a cylinder having a circumferential extent in excess of 180 whereby the seats permit the blocks to rock therein while preventing radial inward movement of the said blocks.

It will be noted'that the space between the outer wall 7 and the segmental inner wall 7 is divided into a plurality of chambers C, said chambers being separated from each other by means of the side walls of the seats B and by the bearing blocks'inse-rted within such seats. Each chamber C adapted to communicate with the interior of the seats B on each side thereof through large openings 9 formed in thewalls of said seats, thereby to lubricate the outer surfaces of the bearing blocks; The chambers C are enabled to communicate with each other and to provide for the circulation of the lubricant by cent'rifugalaction, by means 'of the ports 10, formed in the outer portions of the seats, said'ports forming passa es'beyond the trunnions connecting the adjacent chambers Cl The ports 10 merge at their inner ends with the openings 9. Fors the purpose of supplying the chambers with lubricant, one such chamber is provided with a filling opening C closed by a plug.

Cooperating with the seats Bare the bear- 7 'ing blocks, each of which is indicated generally at D, the lengthsof. the blocks being equal to the depthsof the seats andbeing so shaped as to fit within the said seats. and

loo

each having an external wall 1110f the same g lleral contouras the wall ot ts Se t cept as such contour is modified by the extension of a cylindrical radial bore 12 therethrough.

Between each bearing block and the ad- 5 j acent shoulder 45* on the adjacentyoke arm,

and surronndingeeach trunnion, is a Washer Each bearing block is provided With a portikkadaptedito register With the ports 210 and iformiitherewith va a continuous pas- 1 sage extending across the end of each trunnion and between the same and the cooperating part of the seat;D ,rthe ports Hand 14 connecting adjacent chambers G. fThe 15 ports 1.0 and 14:. communicate with. a. central lax'iail chamber :15 extending inwardly from the outer end of each. trunnion, from .Which :chanlber Y a port l'6nextends .to the seat provided "for .each Jtrnnnion within its "bearing Zblock, i the portsglorextending at .righteangles .to-Ithe .pl-ane oferotation of the ring .as apointefdiont in li y-earlier application referr ed-ItoIhereinbtefore.

For thepurpose ofholding the fblocksfi'n" theireseats and of preventing leakrageefflubrioantaround the ends of said jblocksfl l employ .xvi'th the-ring A: a pair of clamping rings eachihaving ,a circumferenlizill'flange'fllby means.'ofWhieh;-it is threaded upon one side of the :outer cylindrical wall 0f vtheconnectingringaor rmernber, and f vwithv .a; radially extendinggfiange 518 which is adapted to cover the 1 major portion-bf each of lthe blocks'iB there ibeing; a gasket '19 vine eterposed between reach flange and the adj a- 40 cent.sideiaceofthenringVA.
